How do you change front brake rotor Lexus gs 300?

to replace front rotors first remove two bolts that hold on the caliper. use a piece of wire to tie it to the upper strut do NOT let it hang! then remove two bolts that hold on the caliper tray i think they are 17 mm you will need a breaker bar to do this. then take off the rotor sometimes they are rusted so have some penetrating oil and a hammer or rubber mallet to smack them loose.
